Description

A slider internal thread integral molding mold Technical Field

[0001] This utility model relates to the field of mold-related technology, specifically to an integrated molding mold for a slider with internal threads. Background Technology

[0002] In traditional slider product thread processing, most methods involve forming the bottom hole with a mold and then tapping it. This method is costly and inefficient when there are many threaded holes in the product, and it is difficult to guarantee the high precision of the thread, which cannot meet the needs of long-term mass production. With the development of the manufacturing industry, higher requirements have been placed on the precision, efficiency and cost control of slider internal thread forming. Therefore, a new mold structure is needed to solve these problems.

[0003] Based on the above, after thorough comparison and demonstration, our company carried out corresponding technical modifications and developed a slider internal thread integrated molding mold. Summary of the Invention

[0006] The injection molding machine is composed of a fixed mold assembly and a moving mold assembly, and the fixed mold assembly and the moving mold assembly are combined to form a product cavity;

[0007] The thread forming drive assembly is used to form internal threads;

[0008] The thread forming drive assembly includes three servo motors, a pinion, and a thread insert.

[0009] Each of the servo motors is connected to a small gear, and the small gear meshes with the teeth on the threaded insert. The servo motor drives the small gear to rotate, which in turn drives the threaded insert to rotate, thereby forming the internal thread.

[0010] In a preferred embodiment, a signal synchronization unit is further included; a signal synchronization unit is provided between the servo motor and the injection molding machine; when the mold is closed, the injection molding machine sends a signal to the servo motor to drive the thread insert to advance to a predetermined position to start thread forming; when the mold is opened, the servo motor receives a signal to drive the thread insert to retract to its original position so that the product can be demolded.

[0011] In a preferred embodiment, the moving mold assembly of the injection molding machine is further provided with an ejection module for ejecting the product from the product cavity after molding is completed and the mold is opened.

[0012] In a preferred embodiment, the threaded insert is made of a wear-resistant, high-strength alloy material.

[0013] In a preferred embodiment, the servo motor is a high-precision servo motor with a control accuracy of ±0.01°.

[0014] In a preferred embodiment, a positioning device is provided between the fixed mold assembly and the moving mold assembly to ensure accurate alignment during mold closing.

[0015] Due to the application of the above technical solution, the beneficial effects of this application compared with the prior art are as follows:

[0027] Example 1

[0028] Figures 1 and 2 show a slider internal thread integral molding mold according to the present invention, including an injection molding machine 1 and a thread molding drive assembly 2;

[0029] The injection molding machine 1 is composed of a fixed mold assembly and a moving mold assembly, and the fixed mold assembly and the moving mold assembly are combined to form a product cavity;

[0030] The thread forming drive assembly 2 is used to form internal threads;

[0031] The thread forming drive assembly 2 includes three servo motors 3, a pinion 4, and a thread insert 5;

[0032] Each of the servo motors 3 is connected to a small gear 4, and the small gear 4 meshes with the teeth on the threaded pin 5. The servo motor 3 drives the small gear 4 to rotate, thereby driving the threaded pin 5 to rotate and realize the forming of the internal thread.

[0033] It also includes a signal synchronization unit; a signal synchronization unit is provided between the servo motor 3 and the injection molding machine 1; when the mold is closed, the injection molding machine 1 sends a signal to the servo motor 3 to drive the thread insert 5 to advance to a predetermined position to start thread forming; when the mold is opened, the servo motor 3 receives a signal and drives the thread insert 5 to return to its original position so that the product can be demolded.

[0034] To facilitate the removal of the product after processing, the moving mold assembly of the injection molding machine 1 is also equipped with an ejection module for ejecting the product from the product cavity after the mold is opened after molding.

[0035] The threaded insert 5 is made of wear-resistant, high-strength alloy material, and its surface is hardened to improve the service life of the threaded insert 5 and the accuracy of the formed thread.

[0036] The servo motor 3 is a high-precision servo motor with a control accuracy of ±0.01°, which can accurately control the rotation angle and speed of the thread insert 5 to ensure the accuracy of internal thread forming.

[0037] A positioning device is provided between the fixed mold assembly and the moving mold assembly to ensure accurate alignment during mold closing, thereby guaranteeing the dimensional accuracy of the product cavity and the forming quality of the internal thread.

[0038] In practical use, first install the fixed mold assembly and the moving mold assembly on the injection molding machine 1, connect the thread forming drive assembly 2 and the signal synchronization unit, adjust the parameters of the servo motor 3 according to the internal thread specifications to be formed, including the speed and rotation angle, and check whether the thread insert 5 is installed firmly and whether the tooth meshing is normal.

[0039] The mixed material is injected into the mold cavity. During the injection process, the injection pressure, speed and temperature are controlled to ensure that the material fills the cavity evenly.

[0040] After the mold is closed, the injection molding machine 1 sends a start signal to the servo motor 3. The three servo motors 3 drive the pinion 4 to rotate according to the preset program, which in turn drives the thread insert 5 to rotate in the material, and the internal thread is formed. During the forming process, the position and rotation status of the thread insert 5 are monitored and adjusted in real time through the signal synchronization unit.

[0041] After molding is completed, when the mold is opened, the injection machine 1 sends a signal to the servo motor 3, the threaded insert 5 retracts to its original position, and then the molded slider product is ejected from the product cavity of the mold through the ejection module.

[0042] After demolding, the products undergo post-processing such as degreasing and sintering to further improve their performance and dimensional stability. After final inspection, qualified products are packaged and stored.

[0043] The mold of this application can form non-standard thread specifications including M1.2X0.25, M1.4X0.3, M1.6X0.35, M2.0X0.4, and M3.0X0.5. The forming of different thread specifications can be adapted by adjusting the speed and rotation angle of the servo motor and the parameters of the thread insert.

[0044] This application discloses a slider internal thread integral forming mold. Compared with the traditional tapping process, this mold can save about 20% of the cost in long-term mass production, which is obviously advantageous in terms of overall production cost. The internal process efficiency is improved by 10%, the production cycle is reduced, and the production efficiency is improved, which can better meet the market demand for products. Through the precise control of the servo motor 3 and the precision design of the mold, the relevant dimensions of the formed thread basically meet the customer's requirements after sintering treatment, ensuring the high precision of the thread.

[0045] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
